Google Pay-Style Fintech App

@kamran2012

I can help with this, Hi, I will deliver your Google Pay style fintech app for iOS and Android covering the three core flows: instant transfers, bill payments, and QR code payments at point of sale. The backend, admin console, and both store builds will ship together with documented source code and a test suite for every critical payment path. On a recent wallet build, structuring the auth layer as a standalone module made adding PCI DSS compliance later a configuration task, not a rewrite. I will architect yours the same way so biometric auth, 2FA, and encryption sit in a modular security layer ready for future regulation. Questions: 1) Do you have a preferred payment processor or gateway for the transfers and bill payments, or should I recommend one? Looking forward to your response. Best regards, Kamran

Hello! As per your project description, you are looking to build a Google Pay style fintech application for iOS and Android focused on three core payment experiences: instant money transfers, bill payments, and QR based payments at merchant locations. The platform will require a strong security foundation with biometric authentication, two factor authentication, encrypted transactions, and an architecture that can support future regulatory and compliance requirements. I can build the application with secure user onboarding, money transfer workflows, bill payment integrations, QR code generation and scanning, transaction history, biometric authentication, two factor verification, secure API communication, and a scalable backend. The solution can be architected with security and compliance readiness in mind so future requirements such as PCI DSS, PSD2, and local financial regulations can be incorporated without restructuring the entire platform. I have experience developing fintech applications, digital payment platforms, wallet and transaction systems, QR based payment workflows, secure authentication, payment gateway integrations, and cross platform mobile applications. I will focus on creating a fast and intuitive payment experience. Let's connect to discuss your target country, required payment and biller integrations, and whether you already have the banking or payment infrastructure that the application needs to connect with. Best regards, Nikita Gupta

Building a fintech app with instant transfers, bill payments, and QR code checkout requires careful attention to secure, smooth flows and future-proof architecture. I’ve worked on mobile wallets where we integrated biometric logins and two-factor auth on both iOS and Android, plus end-to-end encryption on every transaction. We designed the backend to isolate compliance-sensitive modules, making later PCI DSS and PSD2 certifications straightforward without a rewrite. For your project, I suggest using React Native or Flutter to speed up iOS/Android delivery and maintain consistent UX. On the backend, a serverless API with encrypted database storage keeps performance high and simplifies scaling. For the admin console, a simple React dashboard tied into the API gives real-time transaction tracking and user control. Do you already have a preferred cloud provider, or should we recommend one based on your security requirements? Also, how do you envision handling merchant onboarding and their QR code generation—do you want that integrated into the admin console? I’m ready to start designing the UI/UX and backend architecture to meet your security and convenience goals. Let’s get this launched smoothly and securely.

Google Pay clones break on three fronts: money movement reliability, airtight auth (biometric + 2FA), and regulatory prep. Wallet, bill pay, and QR POS need to hit one backend API, not split logic, or you’ll get drift and security headaches later. I shipped a B2B payments and QR-based POS for a fintech client last year: user wallets, billers, instant transfers, transaction logging, admin console, live mobile apps (NDA—demo on call). My team handles mobile (Flutter for cross-platform release), web admin (React.js), backend (Node.js, PostgreSQL), and API security (JWT, SCA-ready auth, end-to-end payload encryption). Crew managed cloud deploy on AWS with audit logs, upgrades for PCI/PSD2 handled modularly when your compliance gate hits. Will your region require 3DS or tokenization at launch, or should I wire core flows and performance test first? Ready to start once you answer. Pradeep

Your requirement for biometric auth (Face ID/Touch ID) and end-to-end encrypted transfers across iOS and Android is exactly the kind of security-first fintech build we've handled before. At APIE Tech, we've built payment and wallet apps using React Native + Node.js backend — covering UPI-style transfers, QR scan payments, and admin dashboards. We structure the backend so PCI DSS/PSD2 compliance can slot in later without a ground-up rewrite. What we'd deliver: store-ready iOS + Android builds, a cloud-deployed API, merchant console for transaction monitoring, full source with setup docs, and a test suite covering critical payment paths. Timeline: ~60 days for full delivery. Ping me to align on stack preference and any existing API partnerships you have in place.

Hi, **Your fintech platform should be designed around three priorities: secure transactions, frictionless payments, and a scalable architecture that can evolve into a fully compliant digital wallet without major rewrites.** From my understanding, you need an end-to-end payment ecosystem with mobile apps, a secure backend, and an admin portal. The MVP should support **money transfers, bill payments, QR payments, biometric authentication, 2FA, encrypted transactions, and merchant monitoring**, while keeping the architecture ready for future PCI DSS, PSD2, and regulatory compliance. **Proposed Solution** * Flutter (iOS & Android) * FastAPI / NestJS Backend * PostgreSQL * Firebase Authentication & Push Notifications * QR Payment Engine * Admin/Merchant Dashboard * End-to-End Encryption & RBAC **Estimated Timeline:** 16–20 Weeks **Estimated Cost:** ₹5,00,000 (Core MVP) **A few questions:** 1. Which payment gateway/UPI provider will power transfers and bill payments (Razorpay, Cashfree, PayU, Banking APIs, etc.)? 2. Will users have an in-app wallet, or will transactions be processed directly through banking/UPI rails? 3. Do you already have UI/UX designs and compliance requirements, or should those be planned as part of the MVP? **Potential Challenges** * Payment security & fraud prevention * Banking/UPI integration approvals I'd be happy to discuss the architecture and define a phased roadmap before development begins. Best, **Virander**

Hello, "Cross-Platform FinTech Wallet" - instant transfers, bill & QR payments. I’ll develop the app with React Native and Expo, sharing most code between iOS and Android while still delivering native performance. This lets us launch both platforms quickly and keep the codebase clean. The backend will be built with Node.js on AWS, using JWT and encrypted storage to meet PCI DSS and PSD2 readiness, so future compliance adds only config changes. Which payment processor do you prefer to integrate for handling transactions? Looking forward to working with you. Artur Giżycki
